Rail corrosion protection primarily involves applying an anti-corrosion coating to the rail surface. This coating acts as a barrier between the steel rail and external environmental factors, effectively preventing oxidation, rust, and corrosion.

Steel rails, particularly heavy-duty and lifting rails, are commonly made from high-manganese steel, known for its exceptional wear resistance. Compared to standard steel, high-manganese steel offers greater durability and a longer service life under continuous wheel operation. However, in harsh environments with high humidity or exposure to corrosive substances such as hydrochloric acid and alkalis, rails—especially at the waist and base—are highly susceptible to corrosion. Frequent rail replacements in such conditions not only lead to increased downtime but also add significant economic costs.

To address this issue, rail systems operating in such environments require dedicated corrosion protection. The introduction of coated rails provides a reliable solution, extending the lifespan of the track while minimising maintenance and replacement costs.
